Your inputs
Photos, text, names, and calculation inputs are processed in your browser and are not sent to a Haru Tools server. The hosting provider may process connection information such as your IP address, access time, and requested URL when serving pages.
Country detection and language preferences
To choose a default language, the site queries country.is for your country. The provider receives your connection IP; precise location and GPS permissions are not used. Only the country code is cached for six hours, and Haru Tools does not store the IP address. Your chosen language is saved on this device and overrides country detection. A VPN may affect the detected country. If lookup fails, the browser language is used.
Information stored on your device
Favorites and recently used tools are saved in browser storage. Page files may be cached for offline use. Clear records with the button below, or delete all site data through your browser settings.

Connections to price providers
Your browser requests exchange rates from ExchangeRate-API, gold prices from Gold API, and crypto prices from Upbit. These providers may process your IP address and request details. Your amounts, Morse text, and photos are not sent. Exchange rates may be cached on your device for up to 24 hours, with their timestamp shown. Gold and crypto quotes are kept only in the current page’s memory.
External links and changes
External websites have their own privacy policies. We will update this notice if our processing practices change.
